Product Description

Our High Tensile Half Thread (Reduced Shank) Hex Bolt is engineered for critical applications demanding exceptional strength and reliability. Manufactured from alloy steel and heat-treated to achieve Grade 10.9 performance, this bolt offers a minimum tensile strength of 1040 MPa. The partially threaded design provides a non-threaded grip length for precise clamping, preventing loosening under high vibration. The bright and durable Yellow Zinc plating offers excellent corrosion resistance and a distinctive, quality appearance. This bolt is the preferred choice for OEMs, structural engineers, and maintenance teams in the most demanding environments.

Note: The M16x60, M20x80, and M24x100 are our top sellers for structural connections. The thread length is typically calculated as 2.5d + 6mm (e.g., M20 thread length ~ 50mm). Custom dimensions and threading are available.

Application Scenarios

These high-strength bolts are essential for critical connections in:

  • Structural Steel Construction: Used in steel building framework connections, bolted beams, and pre-engineered metal buildings (PEMB) where high clamp force is required.
  • Heavy Machinery and Equipment Manufacturing: Ideal for assembling heavy-duty industrial machinery, crushers, and press machines where vibration resistance is critical.
  • Automotive Chassis and Suspension Systems: Specified by OEMs for high-stress automotive components, suspension linkages, and frame assembly.
  • Wind Tower and Renewable Energy Infrastructure: Employed in flange connections for wind turbine towers and other energy projects demanding fatigue resistance.
  • Bridge and Infrastructure Projects: Used in structural bolting for bridges and highway guardrail systems.
  • Agricultural and Mining Equipment: Essential for high-abuse equipment assembly like tractors, excavators, and bulldozers.
